FRED WV. OOOLEY, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR OF TYVO- THIRDS TO GEORGE T. HONSTAIN, OF SAME PLACE.

FIREPROOF GRAIN-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 683,441, dated October 1, 1901. Application filed February 16 1901. Serial No. 47,641. (No model.)

To all whom it 72mg concern.-

Be it known that I, FRED W. OooLEY, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Fireproof Grain-Elevators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the construction of elevators or grain-storage buildings and bins.

The first object of my invention is to provide a fireproof structure; second, to provide a structure which will be strong and durable; third, to provide a construction which may be rapidly built up either in warm or cold weather with good results; fourth, to provide an arrangement of central and surrounding bins wherein the surrounding bins truss the central bins, and, fifth, to accomplish the above results at a minimum of cost.

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several Views.

Figure 1 is a diagrammatic section taken approximately on the line :11 w of Fig. 2, showing an elevator constructed in accordance with my invention. Fig. 2 is a diagrammatic horizontal section on the line m m of Fig. 1, but on a relatively larger scale. Figs. 3 and at are details, respectively in section and plan,

illustrating the construction of one of the bin-corners marked a in Fig. 2. Figs. 5 and 6 are detail views, respectively in horizontal section and plan, illustrating the construction of one of the intermediate binjoints marked z in Fig. 2; Fig. 7 is a detail in Vertical section on the line m 00 of Fig. 8. Figs. 8 and 9 are details, respectively in section and plan, illustrating the construction of thebin-joints marked 2 in Fig. 2. Fig. 10 is a plan View of one of the bin-joints marked 2 on Fig. 2. Fig. 11 illustrates a modified construction of the joint marked .2

- and illustrated in Figs. 8 and 9, and Fig. 12 is a vertical section on the line 37 .70 of Fig. 11.

The grain-elevator or building itself is made up of one or more (as shown, two) large inside bins a and a plurality of surrounding bins b. In the construction shown, which illustrates a country elevator, the outside bins I) (see Fig. 1) extend from the top to the bottom of the building, while the larger inside bins a are provided with raised bottoms or floors a, below which in the one case an engine-room c and in the other case a driveway or weighing-room c is located. In the construction illustrated an elevator-shaft d and a'small interior grain-bin 6 separate the two large bins a. The elevator-shaft d, which is best illustrated in Fig. 1, extends from below the ground-line to a point above thereof of the building, so that the upper end thereof projects as a tower.

In the diagram View, Fig. l, the numeral 1 indicates an engine,the numeral 2 a platformscale, the numeral 3 hoppers, the numerals 5 and 6 conveyers, and the numerals 7 and 8 grain-distributing spouts, all of the ordinary construction and constituting no part of my invention.

The grain-bins of themselves and regardless of their relative arrangement involve novel features of construct-ion provided in accordance with my noted objects 1, 2, 3, and 5. These bins, which are preferably rectangular, are built up of horizontally-extended series of I-beams and interposed blocks of tiling or other fireproof material, which are held against lateral displacement by the embracing-flanges of the said I-beams. These I-beams are rigidly connected at the corners of the bins by suitable tie-plates.

In the drawings in Figs. 3 to 12, inclusive, the character f indicates the I-beams, which in accordance with one feature of my invention are made up each of a pair of channelbeams placed back to back. These channelbearns may be riveted together or they may be connected simply as hereinafter noted. The character g indicates the tileblocks, which are of ordinary hollow construction and which may be of any suitable dimensions,usually from one to two feet in height. In the construction of the bins a row of tile-blocks oated at are laid, an I-beam is laid on top of the said row,with itsdepending flangesembraeing the upperedgesof said tile-blocks, and another row of tile-blocks is then laid, with their lower ends on the I-beam and between the upturned flanges thereof. This action is of course continued from bottom to top of the bin. 3 and 4,) the I-beams are shown as cut straight across at their adjoining ends, and an L- shaped joint-plate 7c is interlapped between the upturned flanges of said beams and is secured thereto by strong pins 70, passed through the overlapped parts, as best shown in Fig. 7. The pins 70 project into the adjacent cavity of the corner tile-blocks, which overlie and underlie the same, and these cavities are preferably filled with cement, (indi- Thus the pins 70' are secured in working position, and the tile-blocks are reinforced or strengthened at the corners of ;the bin.

blocks g.

. ed beams.

The construction illustrated in Figs. 5 and 6 is substantially the same as that illustrated in Figs. 3 and 4, except that in this intermediate joint a T-shaped joint-iron k is substituted for the joint-iron 7c. The pins 7c are employed in the same manner, and cement y is in the same way and for the same purpose filled into the adjoining cavities of the tile- The joint illustrated in Fig. is the same as that shown in Fig. 6, except that a nearly rectangular joint-plate k is used instead of the T-shaped joint-plate W, and cerrain of the upturned flanges of the abutting I-beams are cut away to permit the said plate k to lie flat against the bodies of the connect- The inwardly-projecting corners of the joint-plates 70 are perforated at ktto afford means for the attachment of truss-rods, to be hereinafter noted.

The construction illustrated in Figs. 8 and 9 which shows the joints 2 is very similar. to that shown in Fig. 10; but this joint connects four abutting Lbeams, and thejoint-plate k therein employed is provided with oppositelylocated perforations formed in parts of the said plate, which plate is countersunk into the upper flangesrof the connected I- beams.

The construction illustrated in Figs. 11

and 12 is intended to be used at the junction of four bin-walls and where a very strong construction is required-such, for instance, as would be required to support a tower'or the base of a bin. This construction is very similar to that illustrated in Figs. 8 and 9, but differs in the following respects: An approximately square joint-plate 70 is employed and the upper flanges of the four abutting I- beams are cut off, so as to allow the plate to beams.

lie fiat against the bodies or webs of the The anchor-pins 7c are employed as before, and cement is filled in around the same in the cavities of the abutting tile-blocks g. The four corners of the plate R7 are thus left projecting into the bins, and upon the To form the corner-joints .2, (see Figs.

same or between the successive plates 7t cornertiles g are secured by cement.

From the construction so far described it is evident that the metal I-beams and jointplates of the outside bins b form a trusswork to the large inner bins a. To still further strengthen the entire structure against lateral or bulging strains, a plurality of trussrods 13 are applied, as illustrated in Fig. 2. These truss-rods p are therein shown as extending diagonally of the bins b, which are subject to bulging strains from the inner bins a. The ends of the same are connected in the perforations k and k of the joint-plates and 70 respectively, and to permit of their adjustments they are shown as provided with ordinary turnbuckles p. In this manner the outer bins b are securely bound together and are caused to form a very rigid trusswork surrounding the large inner bins.

Directing attention again to Fig. 2, it will be noted that the intermediate portions of the relatively large interior bins a are prevented from bulging outward by the dividingwalls of the relatively small surrounding bins, which extend at right angles outward therefrom, and that such walls act as abutments to reinforce the intermediate wall portions of the said large bins a. The truss-rods p rigidly connect these intermediate walls, which serve as abutments, and thus still further strengthen the walls of the said large interior bins a.

The I-beams interposed between the layers of tile-blocks very securely hold the same against lateral movements and give the walls great strength. It is also evident that the construction may be very rapidly built up and that the same when built of iron and tiling is absolutely fireproof.

It willof course be understood that the invention is capable of many modifications other than those above specified.

It will be understood that the term tile or tile-blocks is herein used in a generic sense to include all fireproof orsubstantially fireproof blocks or sections.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. A building of the character described,
